Mine Zcash Ondrej Sika, Slush Pool Bitcoin Meetup Praha, 10.1.2017
Co je Zcash? Inovativni kryptomena která přináší plně anonymní transakce.
Co je to mining Mining neboli tezeni je zpusob, jakym
se u kryptomena distribuuje mezi uzivatele a zaroven hraje klicovou roli pri potvrzovani transakci (skladanych do blocku)
Rozdily a shody v miningu oproti Bitcoinu Shodne vlastnosti •
21 000 000 coinu • 50 coinu kazdych 10 minut • halving po 210 000 blocich (kazde 4 roky) Rozdilne vlastnosti • Algoritmus • Block rate • Mining na CPU a GPU
Algoritmus • Zcash vyuziva Equihash a SHA-256 jako proof of
work • Equhihash - Generalizovany narozeninovy problem • Equihash je pametove narocny algoritmus a proto je mozne znovu tezit na GPU, i na CPU tezit lze, ale je to o rad pomalejsi nez GPU
Block rate • Block kazde 2.5 minuty • Blockreward 12.5
ZEC • maximalni velikost blocku 2MB = cca 8x vice transakci nez bitcoin
Mining na CPU a GPU CPU • az 20 sol/s
(i7 Haswell) • https://github.com/slush0/epycyzm GPU • az 45 sol/s (R 290) • https://github.com/mbevand/silentarmy
Pooly • Flypool ma tretinu hashate site. Dalsi pooly jsou
nic moc, Supernova ma 15 % site. • Dale Zcash tezi Antpool, Nicehash, … • SlushPool je v posledni fazi pred releasem.
